Wood tracking by identification of surface characteristics

Abstract

A “woodprint™” characterization and identification technique unique employs cameras (16), lighting (14), camera interface hardware (18), a computer (20), and / or image processing software to collect and analyze surface characteristics of pieces of wood (8) to track them through an automated production process in real-time with information that is specific to each wood piece (8), such as what machining is required, its value, and / or its destination. When a wood piece (8) reaches a point in the production process where a decision is required, its unique identity is used to retrieve appropriate information previously determined and assigned to the wood piece (8).

TECHNICAL FIELD

[0003] The present invention relates generally to lumber or board tracking and, more particularly, to using unique surface characteristics (“woodprints”) for identifying individual pieces of wood and tracking them through an automated production process with real-time information specific to the pieces or wood such that when a board or other piece of wood reaches a machining operation or decision...
